Hi Ion mentioned the following in his WoWhead interview,
I see a couple of flaws such as - for the players that arent raiding on a schedule will fall behind if its a quest reward from xyz boss to get the buff each week and pugs will be like (please only apply if you have 20% buff etc)
there needs to be an easy catch up for those joining late or missing raids. (what happens if players are benched on certain fights and miss the buff?)
We’re discussing introducing a system that has similar vibes to Reorigination Array back in Uldir, the first raid tier of BFA, except we’ll be leveraging the quest system. It’ll buff players over time. Right now we’re looking at the buff capping out at about 20% increased player power while you’re within that raid and that will also apply to your Warband! That’ll be cool, that’ll be something that if you come in later with your alts, you can have that extra player power across everyone on your account for that content.
